Description

This course provides the basic tools necessary for the functional dimensioning of mechanical systems. After presentation of the one-dimensional dimensioning and its limits, the "3D" geometric tolerancing (GPS), according to the ISO standards, is introduced in order to learn how to read and write a geometric tolerance according to the functional needs of a part in a mechanical system. The study of the hyperstaticity of the mechanism and the connections allows then to set up the functional conditions required to ensure the assembly and the good functioning of the system. The determination of the dimensional and geometric tolerances is then carried out with the help of the implementation and the resolution of the chains of dimensions. Finally, once the parts have been produced, it is necessary to carry out metrological control and to check their conformity with the functional dimensioning.
